' claims. l (c1. 409107)' This' invention relates to improvements in perpetual calendars.` A

An object of the invention resides in providing a perpetual calendar comprising a movable member, 'and a master calendar comprisinga plurality of calendars arranged in sequence, said member havinga plurality of rows of Vindicia arranged on the member, `ea ch row representing' the last two numerals of a year date and the selquential order of a'calendar of'said master'cal'- A` further object ofA this invention is toprovide a calendar in which a dial isrotatablebetween two elements, one of the elements exposing'to view various numerals 'on the dial indicating years and calendar numbers, thedialbeing operated vin conjunction with af'series ,of numbered calendars attached'toV the device. y

yAiurther object of the invention is to provide Va calendar givingthe dates, days ofthe week and days ofthe year from'the year 1800 Vup'to and includingthe year 1999.

; A'further object ofthe invention is to afford advertising facilities, which. advertising 4is done on'the'outside element of thecalendar;

These and other objects of the invention and the means for their attainment will be more ap parent from the following` detailed description, taken in connection with the accompanying drawings, illustrating one embodiment by which the invention may be realized, and in which:`

, Fig. 1v is a. front view of a calendar embodying and employing the invention."

' Fig. 2 isa view showing a calendar embodying and employing, the invention, with the front velement removedto show the rotating disk and the pluralityof master'calendars. vThe drawings show the invention inV one of its forms. The numeral llindicates the outside element'or cover which is provided with two pairs of windows 2 and`2 through which may be seen the'selected number of the year 3 and the corresponding number of master calendar 4. The numerals 3, 4 and 3', 4 appear on dial 5 which is rotatably mounted to insidev element or back 6 at '7." As illustrated in this instance, windows number 3 and 4' are used for the years 1800 to 1899 and 3 and 4 for the years from` 1900 to 1999. The edge ofrdial 5 slightly protrudes as shown in Figure 1 at 3 to facilitate rotation of the disk or dial 5. Dial 5 is provided with four circular and spaced columns 9, 10, 11 and 12. VColumns 11 and 9 represent'respectively,`the year and corresponding numerals for master calendarL 13 for the years from 1900'to'1999. The rsttwo 'Sevenfold fori leap-years, -tlierefore, with `the ter calendarsy are sufcient'tofcover any Apast date changesmay bemade in the"present calendar jforexample, January 1st will appear on master figures ofthe centuries are indicated at A. A'On account oinumerals being read on both sides'v of disk, it; is 'essential to printl all numerals in columnsv 10 and12 in a'direction opposite to those incolumns 9 and 11. The arrangement of 60 thenumeralscontained on the dial or disk-5 can be changed without changing the main purpose of the rcalendar.r `Although lthe drawings show windows pro.- vided to expose the last two numbers of the years, it is understoodthatfthe Windows may be made largerto expose the whole year. Y l g vIt isfurther'understood' that theedg'e of dial A 5 maybe serrated to facilitate manipulation. The numeral 13 represents a series of vmaster calendars.' .Asif/happens,l `the lpossibilitiesvfor i changing of week-days in respect to the days Vof v the month are Sevenfold-for common years and present system of timerecording-,fourteenmasback to the time 'Whenthe' presentzcalendar sys'- tem was adopted and up until such timewhen system. lIt is understoodth'at this inventions() with necessarily slight changesmay be adapted Vfor use with any other yearly timing'systemjrlfhe k'numeral 13 represents a series of fourteen yearly calendars, each numbered ,and each o f which begins on the successive following day, as

on master e calendarl No. 1 on Sunday,

.calendar No.` 2 onfMonday, andonmaster calendar No. 3 on Tuesday, and so on'until Saturday and repeating thesame againfforseven additional master calendars coveringvleap-years;

' The master'calendars v-13 are suitably fas- Ytened to back element 6` as shown,-forvexample by staples 14, but it ifs lunderstood that any other fasteningmeans may b e employed.A The numeral 15k indicates Athe master calendar numberfcorref sponding to numbers shown in columns 9 Aand 11 of the rotatable dalfor disk 5. On the outside element 1 ample space is provided for advertisng purposes and fora picture or illustration 16 if so desired. Suitable perforation 17 for d hanging the device is provided. i

Instructions or directions 18 are provided upon the outside element, preferably on its lower portion. 1 105 VThe disk 5 vmay be rotatably mounted directly nto the back of outside element l.

The arrangement of Vthe numerals contained 'on the dial or disk 5 can be changed without any convenient symbols other than numerals may be employed to distinguish the master calendar.

In the accompanying drawings I have illustrated the invention embodied in one of its practical commercial forms but as this illustration is primarily for purposes of disclosure it will be understood that the invention isnot limited to this particular form of structure and that it may be modied in many'respects Without departure from the true spirit and scope of the invention as herein defined and claimed. I wish it further understood that the terms which I have employed herein are used in a descriptive rather than in a limiting sense, except however for such limitations that may be imposed by the state of the prior art.

claim as new and desire to secure by Letters Patent,-is: Y
